Todd Bridges -- I Make LESS Than $25k Per Year

Todd Bridges is not a wealthy man ... this according to Todd Bridges.

The former "Diff'rent Strokes" actor just filed new docs in his divorce from longtime wife Dori Bridges, stating that he only makes a grand total of $22,500 per year from his career as an actor ... and that's BEFORE TAXES.

It's a bit of a problem for Bridges ... who, in the docs, claims he spends roughly $4,306 per month ... including a $1,520 monthly mortgage payment.

Todd says Dori was making $1,750 per month ... but combined with Todd's income, it still wasn't enough to cover their average monthly spending

It appears the beef is over how much child support Todd will have to ante up.
